    I try your code, And I dont use SQL in my App, I add SQL Library and say "java.lang.RuntimeException: Object should first be initialized (Cursor)."

    This means that the file path is not available. Note that in most cases you do not need this path to work with the selected image.

    Well, it seems as if the file path is a security issue for the latest update of Android. Instead, you should use the input stream via content resolver / openinputstream .. small snippet:

    Code:
    Sub GetStreamFromContentResult(UriString As StringAs InputStream
        
    Dim r As Reflector
        
    Dim Uri As Object
        
    Dim iStream As InputStream
        
    Uri = r.RunStaticMethod("android.net.Uri""parse"Array As Object(UriString), Array As String("java.lang.String"))
        r.Target = r.GetContext
        r.Target = r.RunMethod(
    "getContentResolver")
        iStream = r.RunMethod4( 
    "openInputStream"Array As Object(Uri), Array As String("android.net.Uri"))
        
    Return iStream
    End Sub
    With this, you can easily receive e.g. a PDF

    Code:
    Try
                             
    Dim theTitle As String =getTitleFromContent(ShareString)  ' the approach above using _display_name
                            Dim thePath As String = ah.getTemporaryDirectory ' my way to obtain a writeable path
                            Dim jo As JavaObject
                            
    Dim Inp As InputStream  = GetStreamFromContentResult(ShareString)
                            
    Dim Out As OutputStream = File.OpenOutput(thePath, theTitle, False)
                            
    File.copy2(Inp, Out)
                            Inp.Close
                            Out.Close
                                                    receivedPDF = thePath & 
    "/" & theTitle
                        
    Catch
                            
    Log(":: issue " & LastException)
                        
    End Try
